I Liked the "Jesus" screen saver in the background. There's a lot of people of faith in these forumsin these forums, judging from the e-mails I get, and of people's of many divers faiths too. And many of no stated faith , who are good people, because they chose to be though and demonstrate it in their deeds. I think that is really cool. Good people are Good people! IMHO.
You do so a good job making these simplified cars, they look good and they go together fast. You capture the details well enough to know exactly what your looking at. I liked the way you did the omni directional wheels on the bottom!
I'm tempted to run one of these through Rhino3D to pull out some of the details! I have too much on my plate though. Since you already have a believable one, why bother!
